t fragments from exploding antiaircraft shells.

Law-enforcement officers, and to a. lesser extent `military personnel, are sometimes exposed to fire from lpistols and revolvers. which compels them either to endanger their lives or abandon their mission. Protection against such nre has been persistently attempted by the use of steel. shields or similar means, which, however, have not been successful as body armor worn on the person, because of the great weight of a steel plate capable of resisting penetration of a projectile, Chiey, with a view to the protection of personnel against death or injury from artillery and hand weapons, laminated non-metallic armor plates possessing great resistance to penetration by projectiles (shell fragments, as well as smallcaliber cartridge and bullets from shor-t-barreled weapons) have been developed during World War II. Examples of such body armor plates are the laminated nylon armor plates described in U. S. Patent No. 2,399,184, Heckert, and the laminated glass fabric armor plate disclosed in U. S. Patent No. 2,562,951, Rose and Merritt. Such plates, while possessing ballistic properties quite adequate for the intended purpose, had the drawback Yj of rigidity and stiffness, which is a source of discomfort to the wearer and, yet more importantly,

may prevent him from getting into the proper iiring position in diicult terrain during combat. 'To overcome this drawback of stiffness in body armor plates, it has been suggested, e. g., in

fl-leckert, U. S. Patent No. 2,399,184, at page 4;

column l, and following that the cementing of the laminae may be limited to one or more of the outer edges or to certain portions of the For example, shell fragment-resisting personal armor can be made by leaving portions 4free from adhesive where bending is required, as

at the knee or elbow. It was found, however,

' during actual eld tests that a multi-layered water filled ioxhole, or as the result of fording a stream; the added weight ofabsorbed waterV tends to defeat the very purpose of the armored garment in that it either immobilizes the wearer or compels him to discard the garment in order to continue to fight.

I have found that a comparatively lightweight armored garment, which has the advantages of compactness and water resistance of a resiny bonded structure without the disadvantage of stiffness of a fully laminated armor plate, can be provided by spot-laminating the layers in a regular pattern wherein the laminated areas are transversely aligned and are arranged in spaced rows extending over substantial portions of the area of the armor plate incorporated in the garment. An. armored garment which is spotlaminated in this general manner, described in greater detail hereafter, is ballistically at least the equal of an armored garment protected by solidly laminated stiff armor plates, and yet ilexible enough to enable the wearer to move freely and to assume the proper nring position, in the prone, kneeling, squatting and standing positions.

A preferred material for an armored garment in accordance with the present linvention is tightly woven nylon fabric, resin spot-laminated in from about 9 to about 20 layers, preferably about 12 to 15 layers. However, as will be hereafter more fully appear, my invention is not restricted to the use of nylon material.

It is a principal object of the present invention to provide an armored body garment which aiiords protection to the wearer against the eiects of fragmentation projectiles for some types of small-arms re, without unduly impeding his movements by reason of excessive weight, stiliness, or bulkiness.

Another object of the present invention is an armored jacket which combines relatively light weight, and good ballistic properties.

A further object of the present invention is a construction of an armored jacket which is protected against waterlogging upon exposure to rain or other sources of water encountered on the battle field.

Still another object of the present invention is a resin-bonded laminated armor plate suitable for use in an armored garment, which is charactei-ized by a regular arrangement of aligned spot laminations disposed in a pattern which insures comparative flexibility throughout its area.

Another object of the present invention is an armored jacket of simple construction, which can be relatively inexpensively manufactured in assorted sizes, and which can be quickly put on or taken ol' by the wearer as combat conditi-ons may require.

Other objects of my invention will become apparent as the detailed description of a preferred embodiment of the same proceeds.

The' accompanying drawings illustrate a preferred'em'bodin'ient of my invention,`but should not be deemed to limit the scope of my invention to any particular dimensions, proportions or' front portion, a generally rectangular back portion, and a shoulder portion, the front por- Ztion being disposed at an obtuse angle relative Figure 2 is a side elevation of the armored vest i illustrated in Fig. 1;

Figure 3 is an enlarged sectional View, 'partly- --element for lamination to the armorplate'as shown in the detailed view'of Fig. 3;

More particularly, the armored garment'in 'a'ccordance with the present invention includes a laminated plate lil of tightly woven high tenacity elongatable plastic textile material, such as nylon, yinclosed in a shell VI l, II of lightweight waterresistant material, e. g. coated nylon. The shell 'preferably' surrounds'the outer and inner Surfaces of the armor plate for additional protection against waterlogging; it may be provided with patch pockets I2, y front tabs provided with quick release vsnap fasteners I3, and belt loops I 4 likewise provided with quick release snap fasteners I5 for the purpose of speedily removing'the garment should the wearer find'h'imself in danger of drowning or other reasons for quickly ridding himself of the armored garment.` The edges of the shell are preferably provided with astrong waterand tear-resistant binding I 5. vIn the construction shown, a pair of plackets Il', I1 unites the front and back panels of the vest. It will be understood, of course, that the foregoing tailoring details are subject to many mod-ifications and variations; thus, the material and armor plate may be enclosed in a plain waterproof shell, e. g. of nylon or vinyl material, and stitched to the inside lof a conventional eld jacket (not shown) having a fly front vand a conventional slide fastener and button closure.

A preferred armor plate for inclusion in a garment of thel type above describedconsistvsA of about 9 to 20, preferably l2 to l5 plies of tightly woven high tenacity elongatable plastic material;v

nylon being the preferred material, other strong 4and elongatable plastic textile materials such as strong fine regenerated cellulose fiber of the Fortisan or Durail type are permissible though presently lessl preferred'substitutes. typical nylon fabric suitable for layers to be laminated in accordance with the present invenvtion is lightweight duck cloth, having the following characteristics: ,l

Weave, plain, twoends woven ,as one, 2 picks Woven as one, weight 13-14 oz. per square yard;

Filing, minimum 37 picks off the loom com- -posed of 5 plied threads;

- Breaking strength, minimum 775 lbs. in warp and filling (grab method) 1 -Elongation of'nished cloth, minimum 30% in r warp and 25% in filling.

This cloth, in the preferred form of the present invention, is then cut into sheets or panels of the configuration shown in Fig. 4 of the drawings; each panel includes a generally rectangufifi as shown in Figure 2 of the drawings.

to the back portion. For greater flexibility, I prefer to have left panels I8 and right panels VvI9, hingedntogether along the back in a manner about to be described in greater detail. However,;,it will be understood that the panels may kalsobe ,cutin the general form of a Y, in a Vconfiguration generally corresponding to the outline'of: Figure 4, but without the center back hinge.

-As heretofore indicated, the plies which make up the armored plate are joined together by resin spot-laminations, with the laminated areas of the front and back portions'v being disposed in a regular pattern which insures-ilexibilityi- As shown in Figure 3 of -the drawings, the laminated areas are transversely aligned, i. e. the resin-bonded area A between the outerk layer 2D and the second layer 2| is in alignment with the resin-bonded areasVv underneath, includingv'l-the resin-bonded area A between next-to-last-layer 22' and innermost layer 23. I havefoundthat best results are obtained by an equilateraltriangular configuration ofthe spot laminations, e. g. of a side length of 2". These triangular spot laminations extend over vthe'areasfof;` the front and back portions of each panel' in spaced rows, as shown in detail in Fig. 4, with thesides of the triangles 24 aligned in straight lines, thereby enabling the amor plateto be flexed transversely and along'lines intersecting at lay 60 angle. The spaces or gutters 25 between the rows should be of .substantial width, sayy to insure flexibility; however, the interstices will be less than the maximum linear dimensions of 'advjacent spot laminaticns (e. g., less than vtlf1e'2" side length of thev triangular'spotlaminations specically set forth herein). t also appears from'the arrangement shownin Fig. 4 thatthe triangles `2li are disposed in regular' clusters, wherein at the intersections between any three gutters 25, the tips of six 4triangles 24 Vare assembled in contiguity.

The shoulder portion is preferably laminated in a different pattern from that of the front and back portion, e, g., in a pattern of small circular spots 26, so that the plate may be bent sharply at the shoulder portion to enable the front and back portionsto be joined in vest or jacket form It is necessary that the individual resin spots 26 between the fabric layers be transversely aligned 4throughout the depth of the plate, as otherwise the plate would be stiff.

The lamination resin is preferably applied` to the plies by means of a stencil or printing roll. While- I do not wish to limit the scope of the present invention to any particular resin, I wish to point out that I have obtained highly satisfactory ballistic results by the use of a mixture of approximately equal parts of a phenol formaldehyde resin and polyvinyl butyral resin (safety glass'grade) in a solvent of alcohol and toluene. Such an adhesive resin is sold by Bakelite Corporation as Resin BJ-16320, and by Industrial Tape Corporation as Permacel 1500;.the resin solids content of this adhesive is about 33-37%.

With the spot-lamination pattern arrangement, as above described, the addition of about l0 lparts by weight of resin to each 100 parts by weight of textile material is sufficient to produce good ballistic results. Other resin binders, some of which are enumerated in I-Ieckert, Patent No.

L 253918584, zmay also be employed, kthough probably wv'it'h less :favorable ballistic results.
